[cp-patches] FYI: BoxLayout and SizeRequirements fix

[Roman Kennke]

Hi,

Thanks to some hints on the classpath-ML I was finally able to fill in
the missing pieces in SizeRequirements and rewrite BoxLayout to use this
helper class. This hugely simplifies the BoxLayout class and should fix
most issues with it. (and yes, the example posted in the original
posting now looks like with Sun).

There is still some finetuning needed in both BoxLayout and
SizeRequirements (I added FIXMEs at these places) and lots of room for
optimization in BoxLayout (we can cache most SizeRequirements objects
and the calculated layout). I will look into both during the next days.
